Los Gatos homeowners typically choose from several ADU options based on property layout, lot size, and project goals.
A detached ADU is a standalone structure built separately from the main home, often located in the backyard. This option offers the most privacy and flexibility and is ideal for rental income or independent living.
An attached ADU is connected to the existing residence and usually constructed as a home addition. This option works well when homeowners want to expand living space while maintaining architectural continuity with the main house.
A conversion ADU repurposes an existing garage or interior space into a legal living unit. Conversion ADUs are often the fastest and most cost-effective option because they utilize existing structures and utilities.
Homeowners planning an ADU often explore additional upgrades such as kitchen remodeling in Los Gatos, bathroom remodeling, full home remodeling, or home additions to improve comfort and long-term value.
As an experienced ADU contractor in Los Gatos, we follow a structured, step-by-step process designed to keep projects predictable, organized, and fully code-compliant.
We begin with an in-depth consultation and on-site evaluation of your property. During this phase, we review Los Gatos zoning requirements, setbacks, lot conditions, access points, and existing site constraints. We also discuss your goals, budget, and intended use for the ADU to confirm feasibility and determine the most practical approach for your property.
After confirming feasibility, you receive a detailed proposal outlining the full scope of work, estimated construction timeline, and budget expectations. This step establishes clear expectations early, ensuring transparency around costs, inclusions, and project milestones before moving into design and permitting.
Our architectural and engineering team develops custom ADU plans tailored specifically to your property while complying with Los Gatos building codes, zoning regulations, and energy requirements. Each design prioritizes efficient layouts, functionality, and long-term usability to create a space that feels comfortable, well-planned, and built to last.
We manage the entire permitting process, including plan submissions, revisions, and coordination with the Town of Los Gatos. Our experience with local approval procedures helps reduce delays, respond efficiently to plan-check comments, and keep your project moving forward.
We guide you through selecting finishes, fixtures, and materials that align with your design preferences, durability needs, and overall budget. From flooring and cabinetry to appliances and exterior details, this step helps define the look and feel of your ADU while keeping decisions organized and the project on schedule.
Once permits are approved, construction begins. Our dedicated project managers oversee all phases of construction, including subcontractors, inspections, scheduling, and quality control. This hands-on oversight ensures consistent progress, professional workmanship, and adherence to approved plans.
After construction is complete, we conduct a detailed walkthrough with you and coordinate all required final inspections. This step ensures every detail meets expectations and complies with Los Gatos requirements before final sign-off.
Your ADU is complete, fully approved, and move-in ready. Whether used as a rental unit, guest house, or additional living space for family, your new ADU is built for comfort, functionality, and long-term value in Los Gatos.

Homeowners in Los Gatos typically have several ADU options depending on lot size, zoning requirements, existing structures, and how the space will be used. The most common ADU types include detached ADUs, attached ADUs, and conversion ADUs.
A detached ADU is a standalone structure, usually built in the backyard, offering maximum privacy and flexibility. This option is popular for rental income, independent living, or guest accommodations.
An attached ADU is connected to the main home and is often built as an addition. This option works well when homeowners want to expand livable space while maintaining architectural continuity.
A conversion ADU transforms an existing garage or interior space into a legal dwelling unit and is often the fastest and most cost-effective approach when conditions allow.

Planning and architectural design typically take several weeks, followed by permitting and approvals that can vary based on review cycles and revisions. Construction itself often takes several months depending on the ADU type, size, and finish level.

Garage conversion ADUs are often more affordable since they utilize an existing structure and may reduce foundation and framing work.
Attached ADUs typically fall into a mid-range cost category due to structural integration with the main home.
Detached ADUs usually require a higher investment because they involve new foundations, framing, roofing, and full utility connections.
